After a week of listening and enjoying the Crown, I came to the conclusion that running the 901's with it was the wrong choice. Today I switched the amps around. Running my 800 watt amp to the 901's and the Crown to my Yorkville speakers. Much better balance this way. For example, previously wired, the gains on the AP800 were set to around 1 maybe 2 oclock to match the Crowns gain of full out. Even still the 901's were being over powered by the Elites. Switching the amps around allows me to run both amps full out with a better blend between the two. IMO the 901's needed the extra power, rather than the pro speaks. With that being said, the XLS 1000 is being driven a lot less than when hooked up to the 901's.
